Sugar molecules coat every cell in our bodies and play critical roles in development and disease, yet the components of these "glycans" have been difficult for scientists to study, because of their complexity.

Researchers at Emory University School of Medicine have adapted gene chip microarray technology to the study of glycans, with an approach they call "shotgun glycomics." The Emory team has developed a new chemical method for attaching a fluorescent dye to glycans purified from cells. The individual glycans are separated into tiny spots fixed to glass slides.

University of Illinois at Chicago researcher Dr. John Quigley will describe a promising new approach to blocking malaria transmission during the American Society of Hematology's annual meeting in Orlando, Fla.

His abstract, "Anopheline Orthologs of the Human Erythroid Heme Exporter, FLVCR, Export Heme: Potential Targets to Inhibit Plasmodium Transmission," will be presented at the plenary session Sunday.

Randomized phase III studies should be designed to find out whether a new drug or treatment makes a meaningful difference in patients' survival or quality of life, according to a commentary published online December 3rd in The Journal of the National Cancer Institute. Instead, most trials now are designed to detect a statistically significant difference between treatment and control groups, which may not be clinically meaningful, write Alberto Ocana, M.D., Ph.D. and Ian F. Tannock, M.D., Ph.D., of Princess Margaret Hospital in Toronto.

Madrid, 2 december 2010.- Spanish Oncology has established a new standard treatment for Breast Cancer at early stages thanks to the results of the study 9805/Target 0 funded by Spanish Breast Cancer Research Group (GEICAM) and sponsored by Sanofi Aventis.

December 2, 2010 – (BRONX, NY) – Nearly a quarter of Americans live in rural areas, which consistently report higher cancer mortality rates than urban and suburban areas. Among the complex causes for this disparity is that only 10 percent of physicians practice in rural areas and almost 4 out of 10 rural residents live at least an hour from an urban area.

DALLAS – Dec. 3, 2010 – Thanks to findings by UT Southwestern Medical Center researchers, individuals with a potentially life-threatening condition predisposing them to blood clots, or thrombosis, might someday receive therapy to prevent the condition.
